The Spine

 


The spine has 5 different sections. The cervical area makes up the neck and has 7 vertibrae, thoracic has 12 which the ribs attach to, lumbar has 5 which make the lower back. The sacrum consists of 5 bones which are fused or stuck together and the coccyx is made up of 4 tiny bones and used to be a tail.

Each vertibrae is separated by intervertibral discs which are flexible cartilage discs. These allow movement in the spine and have a shock absorbing or cushioning function as well.

Each disc is made up of two parts, a tougher fibrous outside and a central substance called nucleus pulposus. When a disc is damaged (or prolapsed) it is the squidgy liquid in the middle which often squeezes out putting pressure on the spinal cord causing pain.
